The cell potential `(E_(cell))` of a reaction is related as `/_\G=-nF E_(cell)`, where `/_\`G represents max. useful electrical work
n=no. of moles of electrons exchanged during the section
for reversible cell reaction `d(/_\G)=(/_\_rV)dp-(/_\_rS),dT`
at constant pressure `d(/_\G)=-(/_\_rS).dT`
:' At constant pressure `/_\G=/_\H-T./_\S`
:. /_\G=/+\H+T(d(/_\G))/((dT)_P)`
`((dE_(cell))/(dT))_P` is known as temperture coefficient of the e.m.f of the cell.
